WINDOW SILLS INTERNAL

Window sills made of natural stone result in a sustainable finishing of your window frame and provides the building or office a luxurious appearance. Since the 1950’s, Nibo Stone delivers no less than 9 types of high-quality natural stones in granite, basalt, marble and bluestone. Besides, we deliver these window sills in two types of composites. These materials are imported weekly by Nibo Stone from quarries all over the world. We have a very strict control system, called the Intern Quality System. Therefore the continuity of our stock is guaranteed, just like the high quality which can not be equalled by any other building material.

The window sills are custom-made in our very own stonemason’s yard and, if desired, provided with miters and/or recesses. The top and front are polished or honed (depends on the choice of materials) and provided with a beveled edge. The heads can be finished optional as well and we also can deliver the window sills with a protective film to guarantee a scratch-free placement in your building. Of course, the manufacturing in deviating natural stones, finishings and sizes is possible.

In order to guarantee the quality of our natural stones, we import our materials directly from quarries all over the world
